Multi-center, prospective nonrandomized study of treatment for 1 and 2 level degenerative disc disease between L2 and S1. Patients will be followed for a minimum of 2 years.

The primary objective of this study to measure fusion success in patients with lumbar degenerative disc disease using the ATB and ALIF/FRA Spacer. The Secondary objective is evaluation of the patient's quality of life, pain and function.

Primary Outcome Measures:
  • Radiographic fusion [ Time Frame: Up to 24 Months ]
    CT Scans and plain film x-rays will be evaluated. Demonstration of bridging trabecular bone through or external to the allograft spacer will be the measure of success.

Secondary Outcome Measures:
  • Quality of Life using the SF-12 Scale [ Time Frame: up to 24 months ]
  • Pain Scores on the Visual Analog Scale [ Time Frame: Up to 24 months ]
  • Functional improvement using the Oswestry Disability Index [ Time Frame: up to 24 months ]

Enrollment: 150
Study Start Date: April 2004
Study Completion Date: February 2011
Primary Completion Date: May 2009 (Final data collection date for primary outcome measure)

Inclusion Criteria:

  1. One or Two level (consecutive) degenerative disc disease between L2 and S1. Degenerative disc disease is defined as follows:

    Chronic pain (confirmed by patient exams and history) of discogenic origin, confirmed by radiographic evidence (e.g. MRI, discogram) two or more of the following:

    • Modic type 2 endplate changes on T2 weighted MRI
    • high intensity zone signal on T2 weighted MRI
    • positive discogram with negative controls
    • dark disc (diminished T2 weighted signal)
    • decreased disc height
  2. Has experienced pain, functional deficit and/or neurological deficit for a minimum six month period of time prior to enrollment
  3. Has failed to respond to non-operative treatment modalities for a minimum three month period of time prior to enrollment
  4. Skeletally mature and at least 18 years of age
  5. Signs the approved Informed Consent Document
  6. Is available for long term follow-up and interval visits

Exclusion Criteria:

  1. Has more than 2 levels to be instrumented
  2. Has had a previous fusion attempt at the involved level(s)
  3. Has had more than two previous open, lumbar spine surgical procedures at the involved level(s)
  4. Currently implanted with anterior instrumentation at the involved level(s)
  5. Patient would be classified as morbidly obese BMI > 35
  6. Active localized or systemic infection
  7. Presence of a disease entity or condition which significantly affects the possibility of bony fusion (e.g., osteoporosis, metastatic cancer, long-term use of steroids, etc.)
  8. Has an immunosuppressive disorder
  9. Pregnant or interested in becoming pregnant during the study.
  10. Has a known sensitivity to device materials
  11. Mentally incompetent or prisoner
